我有这个包含以下内容的csv文件（test.csv）：
from pyspark.sql.types import *
data = sc.textFile('test.csv')\
.map(lambda s: s.split(";"))\
.filter(lambda v: v[0] != 'COLUMN_STRING') \
.map(lambda v: (v[0], int(v[1]), v[2]))
schema = StructType([StructField('COLUMN_STRING',StringType(),False),
StructField('COLUMN_INT',IntegerType(),False),
StructField('COLUMN_TIMESTAMP',TimestampType(),False)])
df = sqlContext.createDataFrame(data, schema)
df.take(2)
我尝试使用以下代码将第3列时间戳yyyyMMddhhmmss导入TimestampType（）：

当我在Spark 1.6.3群集（HDP3.5）上运行PySpark3时，我收到有关＆＃34;＆＃39; str＆＃39;对象没有属性＆＃39; tzinfo＆＃39;＆＃34; ...
这是一个简化的例子。我必须找到如何在TimestampType（）中导入这样的yyyyMMddhhmmss而不改变原始数据，因为这是一个简化的测试（我的实际数据很大，因此修改源代码不是一个选项）。
我在下面提供了错误消息。
任何帮助表示感谢/谢谢，MT

Schema应该反映你拥有的类型，所以如果你想使用RDD，你应该首先解析它：
.map(lambda v: (
v[0], int(v[1]), datetime.datetime.strptime(v[2], "%Y%m%d%H%M%S")))
